In the usual method of brain removal in forensic autopsies, the upper bridging veins were invariably torn. There are several types of head injuries, in which ruptures of these vessels are the predominant intracranial injury. For the past 5 years we have investigated nearly all cases of lethal head injuries by a simple X-ray method (axial X-ray after instillation of contrast material into the superior sagittal sinus). The evaluation of the 350 X-rays which were available until today can be summarized by the following statements. (a) Anatomy of the parasagittal bridging veins: regarding the numbers and diameters of the veins, we can separate cases with many bridging veins of small diameter from a group with few veins of a large diameter. (b) Causes of injury and direction of impact: bridging vein ruptures resulted more often from frontal than from occipital, parietal and lateral impacts and occurred in traffic accidents in the majority of our cases.
在法医尸检中通常的脑取出方法中，上桥静脉总是会被撕裂。有几种类型的头部损伤，其中这些血管的破裂是主要的颅内损伤。在过去5年里，我们通过一种简单的X射线方法（向上矢状窦内注入造影剂后进行轴向X射线检查）对几乎所有致命头部损伤病例进行了调查。对至今可得的350张X射线片的评估可归纳如下。(a) 矢状窦旁桥静脉的解剖结构：关于静脉的数量和直径，我们可以将直径小的桥静脉多的病例与直径大的桥静脉少的病例区分开来。(b) 损伤原因和撞击方向：桥静脉破裂更多是由额部撞击而非枕部、顶部和侧面撞击导致的，并且在我们的大多数病例中发生在交通事故中。
